cpufreq_out_of_sync(9)

🎀 NAME 🎀

cpufreq_out_of_sync — fix up actual and saved CPU frequency difference. 💅 This is the cpufreq_out_of_sync(9) page from the Kernel API Manual, and it's lowkey giving “tiny kernel helper with one very specific job” energy. ✨

🌸 SYNOPSIS 🌸

void cpufreq_out_of_sync (struct cpufreq_policy *policy , unsigned int
       new_freq );

🦋 ARGUMENTS 🦋

• policy — policy managing CPUs. Like, the policy that's managing the CPUs, periodt. 👑
• new_freq — new CPU frequency. The fresh frequency value, bestie. ✨

🔥 DESCRIPTION 🔥

Okay so the whole vibe is: adjust to the current frequency first, and clean up later by either calling cpufreq_update_policy, or scheduling handle_update. That's literally it — first the adjustment happens, then the cleanup happens later through one of those two paths. 🫶 No cap.
